Ok, the only reason i bought these is because my other ones broke (i own a PDP double bass pedal) and they seem to be much better than the ones i had previously (i don't know the brand of the other ones!). They adjust very easily, they were very easy to install and now i hope they last more than 4 years. But hey, for the money these aren't a bad deal at all. I would highly recommend these!

P.S. Just don't wait until both springs break, then you can't play drums until they ship to you!
